Whether logistics center or functional industrial roof - flat roofs are used today to generate added value for the building owner and the environment. Under suitable conditions, flat roofs offer an excellent opportunity to transform protective roofs into usable roofs. Nowadays, building owners no longer have to choose between photovoltaic systems and green roofs, as the combination of both options is possible and particularly advantageous. Due to the increased requirements and multiple uses, a permanently watertight flat roof is essential.

The challenges of permanently sealing utility flat roofs

In order to meet the requirements for sealing flat roofs for private and industrial use, manufacturers of plastic roof membranes and manufacturers of welding machines, as well as experts and roofers, are faced with the following challenges in particular:

  • How are tightly welded seams or seam joints achieved using plastic waterproofing membranes on flat roofs?
  • In addition to temperature, speed and pressure, what must be taken into account when joining waterproofing membranes with roof welding machines (extended welding triangle)?
  • How are the welding parameters ideally set in order to produce sustainable or permanently tight weld seams?
  • Material manufacturers recommend test welds. What needs to be considered during a test weld and how is it performed correctly?
